TONSIL v HEMOSTAT.

Application led October 20, 1923` Serial No. 669,756.

To all fen/tom t may concern: l

Be it known that I, DONALD MCKAY, a subject of the King of GreatBritain, and a resident of the town of Collingwood, in the county ofSimcoe, in the Province of Ontario, Canada, have invented certain newand useful Improvements in Tonsil Hemostats, of which the following isthe specification.

My invention relates to improvements in tonsil hemostat and the objectof the invention is to devise a. hemostat which may be readily insertedand adjusted in the proper position within the throat of the patient soas to produce a direct pressure against the tonsil beds and which willthereforev be efficient to a maximum extent and at the same time providea device which may be used without discomfort to the patient,' and itconsists essentially of a pair of pressure plates adapted to fit thecavities or beds formed by the removal of the tonsils, means fordetachably securing a covering pad to the plates, stems extending inwardfrom the plates and telescopically engaging one with the other,detachable means for locking the stems in any position to which they maybe adjusted longitudinally and-'means for'simultaneously releasing suchlocking means and drawing the plates inward free of the tonsil beds, ashereinafter more particularly explained by the following specification.

In the drawings like characters of reference indicate correspondingparts in eachv figure.

1 and 2 indicate plates, the outer surfaces of which are convex. 4Theplates are of such a form as to lit the cavities or beds formed by theremoval of the'tonsils. 3 and 4 are stems extending inwardlyrespectively from each plate 1 and 2. The stem 4v is provided with atubular inner portion as indicated at 5 into which the smaller stem 3slidablyit-s so as to form a telescopic connection. 6 is a longitudinalslot formed in the stem 3 and 7 is a'longitudinal slot-formed in thestem 4. 8 is a sleeve provided at one end with a reduced internaldiameter forming an orifice 9 through which the stem 3 passes. The stem4 extends into the opposite end of the sleeve so as to engage with thestem 3 in an over-l lapping position, as clearly indicated in Figure 2.The stem 3 is provided with a series of ratchet teeth 10, the verticalface` of each tooth facing inward.

11 are teeth which are formed in the stem 4 vand correspond in form tothe teeth 10. 12 is a spring locking member comprising a vstrip ofmetal` secured vby a cross rivet 13,

- teeth 10 and 11. 16 and 17 are eyes extending from the plates 1 and 2.18 and 19 are levers extending around the sleeve 8 in proximity toeachend. thereof and provided with a cross bar portion `20 extendingcross-wise of the sleeveY 8 through a recess 8x formed therein, therebyextending vdirectly beneath the free end of the spring locking member12.

The levers 18 and 19 incline inward and have attached to their innerends operating cords 21 and 22 which extend from the operating ends ofthe levers 18 and 19v through the eyes 16 and 17, and when the device isin position in the throat extend out through the mouth of the patient.23 are gauze pads which are `folded around the plates 1 and 2 and aresecured in position bv the following device: Y 24 are plates Which arepreferably formed of thin springy metal and divided into' two members24X and 24 pivotally connected to- Y side face of each stem 3 and 4 orin a position at right angles to the teeth 10 and 11.

The teeth 29 are set in an opposite direction to the teeth 3 and 4, thatis to say with a vertical face of the tooth facing outward. `When thegauze pad is wrapped around the edge of the plate 1 or 2 the free endsof the gauze are folded inward and the plate 24 forced against the edgesof the gauze so as to clamp them between the plate 24 and the plate 1 or2. rEhe plate 24 is also provided with inturned projections 30 whichengage the gauze and serve to provide a clamping hold thereon.

l/Vhen removing' the pad all that is necessary to do is to spread thefree ends of the divided portions 24X and 240 of the plates 24 apart soas to free them from the ratchet teet-h 29 and permit the plates beingslid longitudinally of the stem 3 or 4 so as to disengage the pad.

31 are pressure springs extending between the ends of the sleeve 3 andthe plates 24 .exerting an outward pressure against such plates so as toresiliently hold a pad in contact with the tonsil beds. The ends of thesleeve S are preferably notched as indicated at 8 so as to relieve theinturned ends 14 and 15 of the spring locking member 12 from contactwith the springs 31.

Having' described the principal parts involved in my invention 1 willbriefly describe the operation of the same.

After the pads have been placed upon the plates 1 and 2 as abovedescribed, the cords 21 and 22 are drawn upon so as to carry theinturned ends 14 and 15 out of contact with the teeth 10 and 11 of thestems 3 and 4, permitting;- the stems to be slid longitudinally inwardof the sleeve 8. The sleeve 8 is then gripped by a pair of forceps andthe hemostat inserted in the throat of the patient. Each stem is thendrawn outward by another pair of forceps so as to successively force theplates 1 aud 2 and the pads carried thereby into contact with the tonsilbeds, the inturned ends 14 and 15 slipping over the ratchet teeth 10 and11 during this operation. /Vhen the plates 1 and 2 and the pads are inposition the inturned ends 14 and 15 engage the shoulders formed by thevertical faces of the teeth 10 and 11., thereby holding the padssecurely in position in the tonsil beds to prevent further bleeding.

The springs 31 serve to exert a resilient pressure so that the padsaccurately accommodate themselves to the depth of the bed. When it isdesired to remove the hemostat all that is necessary to do is to pullupon the cords 21 and 22, thereby swinging' the levers 18 and 19 towardsa position at right angles to the longitudinal centre of the sleeve 8,thereby lifting the free ends of the spring locking member 12 out ofengagement with the teeth 10 and 11 of the stems 3 and 4.

The pull upon the cords 2l and 22 also exerts an inward draw upon theplates 1 and 2 so that immediately the stems 3 and 4 are released, suchplates are drawn inward and out of the tonsil beds, permitting theinstrument to be drawn out of position through the mouth of the patientIn Figure 6 1 have shown a modified form of pressure plate. 1n this formthe plate or member is formed by a strip of fiat spring` wire wound intoa helical coil7 the innerA end of the wire being connected to a centralstem` and the end of the outer turn to the next adjacent turn. By thismeans a pressure member is formed which will accommodate itself exactlyto the formation of the tonsil bed. 1t will of course be understood thata pad such as previously described in connection with the foregoing`construction is also applied to the construction shown in Figure 6.

From this description'it will be seen that 1 have devised a very simpledevice which is very eiiicient for the stopping of hemorrhages occurringafter the removal of tonsils, by producing` a direct and even pressureinto the tonsil bed, and which may be readily adjusted into position andwhich cbviates the use of any device not forming part of the hemostatwhich is held in the mouth of the patient during the time that thehemostat is in position within the throat, and therefore preventing the4faggefing eifect and the consequent discomfort to the patient duringthe time that thehemostat is within the throat.

What I claim as my invention is:

1. In a tonsil hemostat, a pressure plate adapted to support a pad andto fit a tonsil bed, means engaging the opposite side of the throat,means located between such engaging means and the pressure for forcingthe pressure into the tonsil bed, and a pull cord operable from theexterior of the patients mouth for withdrawing the pressure plate out ofengagement with the bed.

2. In a tonsil hemostat, a pair of oppositelv directed. plates adaptedto carry pads fitting the tonsil beds at each side of the throat,resilient means for forcing the plates apart. releasable locking meansfor holding): the plates in the spread apart position and Horrible meansoperable from the exterior of the patients throat for simultaneouslyreleasing the locking'` means and withdrawing' the plates out ofengagement with the tonsil beds. i.

3. In a tonsil hemostat, a pair of plates adapted to carry pads engagingthe tonsil beds, stems extendinginward from the plates telescopicallyengaging one with the other, a covering sleeve extending around theengagging' portions of' the stems. means carried by the sleeve forlocking the stems in the adjusted position. means for limitingY theoutward movement of the stems, and means operable from the exterior ofthe patients throat for simultaneously releasing such locking means andwithdrawing the plates trom the tonsil beds.

4. In a tonsil heinostat, a central sleeve, a pair of stems slidablewithin the sleeves, means for detaohabiy looking the stems in anyposition to which they may be adjusted and pad bearing means carried atthe ends of the stems for engagement with the tonsil beds.

In a tonsil hemostat, a central sleeve, stems slidable within thesleeve and extending outward from each end thereof, a ratchet rackJformed on each stem, a spring locking member carried by the sleeve inengagement with each ratchet rack, means operable from the exterior ofthe mouth of the patient for withdrawing the inner portion of thelooking members simultaneously out of engagement with the racks and padbearing means Carried at the outer ends of each stem.

6. In a tonsil hemostat, a pressure plate adapted to tit a tonsil bedand over the exterior face of which a pad is adapted to be held so as tobe folded around the edges of the plate against the inner4 face thereof,a stem extending outward from the pressure plate and a gripping platedivided into two portions and extending around the stem, means forengaging the gripping plate with the stem in yany position to which thegripping plate is adjusted, and resilient means vfor holding the membersof the gripping plate together.

7. In a tonsil hemostat, a pressure plate over the exterior yface ofwhich a padv is adapted to be held so as to fold around the edges of theplate against the interior face of the plate, a stem extending from thepressure plate, a ratchet rack formed on the stem, a gripping platedivided into two portions pivotally connected together so as to itaround the stem and against the inner face lof the pressure plate toengage the edges of the pad, projections extending inward rom thegripping plate to engage the pad and resilient means for holding lthefree ends of the gripping plate members together.
